The only time I've had flakiness like what you've described is because of batteries and one I replaced because it just went haywire after the kids dropped it a couple of times onto a hard floor surface. We've got three trackpads - a bad batch of batteries can make it hard to identify what the issue is.

Not much help, I know.
Thanks for your response. It is not a battery issue.
